When using 'virsh attach-device' to hotplug an unsupported console type into a qemu guest, the attachment will erroneously allows the attachment. This patch will check to ensure that only the support target types are used for a running guest. NB, Although a guest can be defined with an improper target, startup will cause failure.
I tweaked the subject and commit message as some sentences didn't make sense.

ACK, although the rest of the chardev command and hotplug code is a big mess and would benefit from a cleanup/refactor. Pushed. Peter
